Market Access Map has been developed by ITC to support the needs of exporters, trade support institutions, trade policy makers and academic institutions in developing countries. It provides information about customs tariffs (including tariff preferences) applied by 196 countries and faced by 239 countries and territories. It also covers tariff rate quotas, trade remedies, rules and certificates of origin, bound tariffs of WTO members, non-tariff measures and trade flows to help users prioritize and analyse export markets as well as prepare for market access negotiations. Users can also find ad-valorem equivalents for all non ad-valorem duties and perform aggregations of products and countries as well as simulate tariff reduction scenarios.

Market Access Map is free to users in developing countries and their representations abroad thanks to generous support from the European Commission, DFID, the World Bank and donors to ITC's trust fund.
